The collection Sacra et litaniae was first published in a Jesuit printing house at the Prague Clementinum in 1654.  Like the other parts of this largest Czech collection of Latin liturgical music, Michna's Mass No. 4 is published for the first time in a new critical edition by Professor V. Belsky (notation) and Dr Jiri Sehnal (text, edition supervisor).<br>

Mass No. 4 was written for solo voice (canto), i.e. preferably a good boy soprano, mixed choir, strings and continuo.  The violas may also be replaced by trombones of smaller dimension.  The piece is relatively concise and intimate, the violins only appear in a few opening bars, the so-called Sinfonia, thus the instrumental accompaniment of the remainder of the piece acquires an unusual muted character.<br>
